AIR-PUMP.

Specification of Letters Patent.

Patented Dec. 26, 1918.

Application filed February 5, 1916. Serial No. 76,498.

To all whom it may concern Be it known that 1, CHARLES CAREY MAN- nnn, a citizen of the United States, residing at Ogden, county of l/Veber, State of Utah, have invented a new and useful Improvement in Air-Pumps, of which the following is a specification.

My invention relates to an air pump and more particularly to an air pump to be used in conjunction with a carbureter to automatically supply air to the same and which is particularly adapted to carburet' air for illuminating and general household purposes.

The principal object of the present invention is to provide an air pump to be used in conjunction with the carbureter which is automatically operated, that is, after the supply of carbureted air has been diminished, the pump and carburetor will operate to form a new supply.

A further object of the invention is to combine an air pump with a carbureter and a vertically movable storage bell for containing the carbureted air, all of which are automatically operated when the supply of carbureted air is being diminished, to replenish the supply.

A still further object of my invention is to provide a valve arrangement which consists of a primary valve which controls a fluid under pressure that is operatively connected with the carbureter, and a secondary valve which is controlled by the primary valve, which controls the operation of the mechanism for drawing air into the carbureter.

An additional object is to provide an apparatus of the above entioned character which is simple in construction, consists of which may be placed on the market at a comparatively low cost.

With the above and other objects in view, the invention consists of the combinations, arrangements of parts and operations that will be explicitly set forth in the following description and illustrated in the accompanying drawings, in which Figure 1 is a longitudinal sectional view through the apparatus. Fig. 2 is a transverse sectional view on the line 2-2 of Fig. 1. Fig. 3 is a detail view of the buoyant mixer and certain parts that operate therewith. Fig. 4 is a view taken on the line 33 of Fig. 3. Fig. 5 is a longitudinal sec tional view of the secondary valve arrangement used in conjunction with the apparatus, this view being taken on the line ings, the numeral 5 indicates a tank or casing which sets on a base or rim 6 and has mounted upon the interior thereof at diametrically opposite points vertically extending tracks 7 having the inwardly turned stops 8 at their lower ends.

Mounted in the tank 5 is a vertically movable bell 9 having grooved rollers 10 mounted thereon which ride on the tracks 7. Arranged centrally of the tank 5 and extending vertically within the same is a cylinder 11 having a cap l2threaded upon its upper end and provided with a. port 12. The lower end of this cylinder 11 extends through the bottom of the tank and is threaded in a hollow connection 13.

Mounted in the cylinder 11 is a piston rod 1 1 having a piston 15 upon its lower end and a plate 16 upon its upper end which is secured to a hood 17 that moves verticallywithin the bell 9. Positioned within the hood 17 is one end of an L-shaped conducting pipe 18, the lower end of which extends through the casing or tank 5 and communicates with the atmosphere and has mounted therein a check valve 19 which allows air to pass into the pipe 18 but prevents it from escaping therefrom.

Arranged in the tank 5 is a carbureting chamber or receptacle 20 having openings in the bottom and top thereof which snugly receive the cylinder 11. Positioned upon this cylinder 11 is a snugly fitting tubular supporting member 21 having flanges 22 upon each end which engage the bottom and top of the chamber 20. Communicating with the chamber 20, at any point adjacent the bottom thereof, is a liquid fuel inlet pipe 23.

Mounted on the tubular supporting member 21 and vertically movable thereon is a buoyant member 24:- Arranged centrally of this buoyant member 24 is a tubular member which includes an inner wall 25 and an outer wall 26 which are connected together at the top by a wall 27. This tubular member is mounted on the tubular member 21 and moves vertically thereon and is provided at its lower end with openings 29 that communicate with of the valve rod, that is, the end that extends 1 within the chamber 41, is a hollow cylina mixing chamber 30 in the buoyant member 24. Secured to the wall 26 is a plurality of blades 28. Positioned onthe wall 26 is an air deflecting plate 29. Arranged at the bottom of the carbureter 20 and surround ing the tubular member 21 is a tubular air conducting member 31 having inner and outer spaced walls 32 and 32. Communicating with these spaced walls at the lower end thereof is an L-shaped pipe 33 which extends through the top wall of the receptacle 20 and withinthe hood 17 to conduct air contained in said hood to the tubular air conducting member 31. Extending transversely through the walls 32 of the member 31 is a liquid fuel conduit 57 which allows the liquid to pass up through the member 31 and thence through the openings 29 and into the mixing chamber 30 of the buoyant member 24. It will be seen that the air from the air conducting member 3], which conducts air from the hood 17, will also escape through the openings 7 29 which will cause the buoyant member 24 to rotate thereby thoroughly mixing the air and liquid fuel together.

The numeral 34 denotes a substantially U-shaped pipe, one end of which extends within the receptacle 20 and almost to the top of the same while its opposite end extends verticallywithin the bell 9. Extending within the bell 9 is an outlet pipe 35 which may be connected with any storage tank or the generalservice pipe.

.Disposed acrossthe top of the tank or casing 5 and down along the side thereof is a pipe 36 which conducts steam, water or 'air under pressure. Arranged in this pipe 36 is a valve 37 having an arm 38 extending therefrom. Mounted on the top of the bell 9 is a standard 39 having pins 40 arranged thereon, between which is disposed the free end of the arm 38.

In conjunction with the pump and carbureter, a novel form of valve is used which shall be set forth in detail and referred to as the secondary valve. This secondary valve includes a relatively large valve chamber 41 and a piston chamber 42 which are connected together by plates 43 that are cast integral with the'inner ends of these chambers. The outer ends of these chambers are closed by end plates. The chamber 41 is provided with jackets 44 which communicate with ports 52 and 53 formed in the chamber 41. Extending through the plates 43 is a valve rod 45 which extends into both of thechambers. Secured to the end of the rod that extends within the chamber 42 is a piston 46. A coil spring 47 is engaged about this end of the valve rod and bears against the piston 46. Secured to the opposite end drical valve member 48 having annular heads 49 and 49 secured to the opposite ends of the same. Arranged on one end of'this valve 48 is a regulator cap 50 which is provided with an aperture. Threaded into a nipple 51 on one of the jackets 44 is the lower end of the pipe 36. Also formed upon one of the jackets 44 is a nipple 52 which receives one'end of a pipe 53 that communicates with the interior of the member 13. Communicating with the cylinder 11' is a pipe 54 which extends through the tank or casing 7 at the lower end thereof and connects with the chamber 42 of the secondary valve, as at 55. p

The operation is as follows: Assuming that the bell 9 is filled with gas, it is-obvious that it is in the position'shown in full lines 7 in Fig. 1 and that as the gas is consumed,

the bell 9 moves downwardly. While the gas contained in the bell 9 is being exhausted, it assumes the position shown in dotted lines in Fig. 1; when it actuates the rod 38 to open the valve 37. This allows fluid under pressure to be forced through the pipe 36 from which it passes through the nipple 51 and into the valve chamber 41 and thence through the nipple 52vby'way of port 52 and into the pipe 53 which communicates with the cylinder 11. The piston 15 is now j moved upwardly which also moves the hood 17 upwardly into the position shown in dotted lines in Fig, 1, thereby drawing air I through the air pipe 18. When this piston has passed the pipe 54 that communicates;

with the cylinder 11 the fluid by way of this pipe escapesto the chamber 42 and moves the piston 46 against the tension of the spring 47'until the annular head 49 passes the ports 52. As the hood l7 gradually moves downwardly by gravity, air is forced through the receptacle 20 where it mixes with the hydrocarbon in the carbureting chamber. During this downward movement the piston 15 forces fluid out of;

the cylinder 11 and into the pipe 53 thence through the ports 52 in the valve chamber 41 and through the interior of the hollow valve 48 and thence out through the opening in the regulator cap 50 and escapesto the atmosphere byv way. of the exhaust. port 56. During the downward movement of thehood 17 an air-pressure of about three ounces per square inch is produced and which is delivered to the storage bell 9 by way of the pipe 34. During such down ward movement, pressure is exerted upon the piston 46 by'way of 12, cylinder '11 and pipe 54 which pressure is suflicient to hold the'pisto-n down against the tension of the tion at the point of use, to permit'the spring;

47 to force the piston 46 upwardly and move the valve 48 into position to again admit motive fluid below the piston 15.

While I have described the preferred embodiment of my invention, it is to be understood that the disclosure is illustrative only and that the invention is susceptible of various modifications that may fall within the scope of the appended claims.

What I claim is:

1. The combination with a tank and a vertically movable bell mounted therein, of a cylinder mounted in the tank and extending vertically therein and provided with an inlet port at one end thereof and an outlet port at its opposite end, a piston and piston rod movable within the cylinder, a hood carried by the piston rod adapted to draw air within the bell upon its upward movement and to force the air into a receptacle upon its downward movement, a valve mechanism controlling a fluid under pres sure and having communication with the inlet and outlet ports, the valve mechanism being actuated to cut ofl the supply of fluid from the cylinder when the piston has passed the outlet port upon its upward movement, the descending of the piston forcing compressed fluid through the outlet to retain the valve mechanism open to exhaust to allow the descent of said bell.

2. The combination with a tank and a vertically movable bell mounted therein, of a hollow member disposed below the bottom of the tank, a cylinder threaded into the hollow member and extending vertically within the tank having a fluid inlet and a fluid outlet, a piston and piston rod movable within the cylinder, a plate mounted upon the upper end of the piston rod, a hood secured to said plate and adapted to draw air within the bell upon its upward movement and to force the air into a receptacle upon its downward movement, a valve mechanism controlling a fluid under pressure and having communication with the inlet and outlet ports, the valve mechanism being actuated to cut off the supply of fluid from the cylinder when the piston has passed the outlet port, the descending of the piston forcing compressed fluid through the outlet to retain the valve mechanism open to exhaust to allow the descent of said bell.
